BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a golf club head, especially to a wood golf club head.

2. Description of Related Art

Golf is a sport in which a player strikes a golf ball with a golf club. The golf ball is struck to a designated position by centrifugal kinetic energy generated during swinging of the golf club. A conventional golf club head is an important part for striking the golf ball.

With reference to FIG. 5, the conventional golf club head has a body 90 and a strike panel 80. The body 90 has a crown, a sole 92, and a side 93. The sole 92 is located below the crown. The side 93 is connected between the crown and the sole 92 to form the hollow body 90. The strike panel 80 is mounted on a front end of the body 90. A hosel 94 is formed on the crown to be connected to a shaft.

The player can hold and swing the shaft for striking the golf ball B′ by the strike panel 80 of the conventional golf club head. A flight path of the golf ball is easily affected by a position of a center of gravity of the conventional golf club head. With reference to FIG. 5, a center of gravity of the body 90 is projected on the strike panel 80 to form a best striking spot. A best striking zone S′ is formed around the best striking spot.

If the position of the center of gravity of the conventional golf club head is deviated from the sweet area, the flight path of the golf ball is shortened. On the contrary, the position of the center of gravity of the conventional golf club head is located at the sweet area, and the flight path of the golf ball is prolonged.

If the position of the center of gravity of the conventional head golf club is close to the hosel 94, a moment of inertia of the golf ball is decreased, and the flight path of the golf ball is shortened, too. If the position of the center of gravity of the conventional head golf club is far from the hosel 94, a moment of inertia of the golf ball is increased. When a striking spot is located at the sweet area, the flight path of the golf ball is prolonged.

With reference to FIG. 5, the hosel 94 is located at the side of the crown, and the center of gravity of the body 90 moves toward the hosel 94. For allowing the golf ball to easily strike on the best striking zone S′ of the golf club head upon striking, and for controlling the striking force and the striking direction easily, counterweight of the sole 92 is increased to adjust the position of the center of gravity of the body 90. The position of the center of gravity of the body 90 is close to a center line L′ vertically passing through a center point C′ of the strike panel 80 and is far from the strike panel 20. The best striking zone S′ is adjusted to be located around the center point C′ of the strike panel 80.

To assist the player in aiming at the striking direction, an aiming point is mounted on the crown and is located in a middle of the strike panel for ease of aiming at the center point C′ of the strike panel 80 upon striking. However, for increasing the counterweight of the sole 92, a counterweight groove is formed on an inner side of the sole 92, and a counterweight block is mounted on the inner side of the sole 92. Production cost of the golf club head is increased. Furthermore, it requires certain skills to adjust a thickness of the sole 92 in a manufacturing process. Otherwise, when the sole 92 is too thick, the golf club head will be overweight, and when the sole 92 is too thin, the center of gravity of the golf club head will be too high. Therefore, how to effectively adjust the position of the center of gravity and simplify design of the counterweight of the gold club head are problems that need to be overcome.

To overcome the shortcomings, the present invention provides a golf club head to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The objective of the invention is to provide a golf club head to solve the problems that the counterweight of the golf club head is not properly disposed and decreases the striking effect.

The golf club head has a body, a strike panel, and at least one counterweight structure. The body is hollow and has a sole, a crown, a side wall, and a hosel. The crown is located above the sole. The side is located between the sole and the crown, is connected to the sole and the crown, and has an outer surface. The hosel is formed on the crown. The strike panel is mounted on a front side of the body, is located between the sole and the crown, and is connected to the sole and the crown. The strike panel, the side wall, the sole, and the crown enclose an inner space of the hollow body. The at least one counterweight structure is mounted on the outer surface of the side wall. Each one of the at least one counterweight structure has multiple meshed recesses disposed at spaced intervals.

In a manufacturing process, the at least one counterweight structure is integrally formed on the side wall of the body by casting or forging. A thickness, a size, and a position of each one of the at least one counterweight structure can be adjusted for adjusting a position of a center of gravity of the body.

The golf club head uses the at least one counterweight structure mounted on the side wall of the body to adjust a position of a center of gravity of the golf club head, and has the following advantages:

1. Adjusting the position of the center of gravity of the golf club head: the at least one counterweight structure is mounted on the outer surface of the side wall of the body.
